I just bought a used 2010 15" MBP a few weeks ago. It is covered with Apple care. First the headphone jack was acting up . I brought it in to the local authorized Mac repair. They replaced the jack and the logic board. I watched a couple of movies on wireless Netflix. Did some audio video recording yesterday. Set it up to watch a movie and it went dark, like in the sleep mode. Battery was near 100%. Back it goes, but man this is a PIA.
